RUDOLF \VITTMANN, OF BROOKLYN, NEW YORK.

CYCLE.

SPECIFICATION forming part of Letters Patent No. 693,202, dated February 1 1, 1902.

Application filed March 29, 1900. Serial No. 10,690. (No model.)

To all whom it may concern:.

Be it known that I, RUDOLF WITTMANN, a citizen of the United States,residinginBrooklyn borough, New York city, in the county of Kings and State of New York, have invented new and useful Improvements in Cycles, of which the following is a specification.

By means of this invention a cycle-frame can be made simple and durable; and theinvention resides in the novel features of construction set forth in the following specifica tion and claims and illustrated in the annexed drawings, in whicl1- Figure 1 is a detail View of the headpiece.

Fig. 2 is a view at right angles to Fig. 1. Fig. Fig. 4 is a section along y y, Fig. 3. Fig. 5 is a side elevation of a cycle-frame embodying my invention.

In the drawings is shown a cycle or vehicle frame of which the branch or section 1 is conveniently called the top branch and 2 the front branch. The intermediate section or seat-post branch is shown at 3, the rear branch or stays at 4, and the lower branch or bottom stays at 5. The rear branch is forked to straddle or extend at both sides of rear wheel 6. The section 4 is also formed of branches on each side of wheel 6, and these sections 4 and 5 are secured or bolted to disks 8, as seen at 9, said disks forming a bearing for wheel 6 or for its axle or hub. The top flange of tube or bar 3 is shown at 10, and the lower end portions of the bars 2 and 3 at section 5 are looped below this section, as seen at 14, to form a pedal or crank-hanger. This hanger or hearing 14 can beheld closed by bolt or fastening 15., i

The headpiece 16, with'itsears or fastening portions 17. and 18, is formed from a single piece of material. The lower tongue 18 is *extendedinto tube 2 and secured by a suitable number of bolts or fastenings. Two bolts have been found to firmly connect the front branch and headpiece. The top section 1 can be pivoted to .or between the lug-sections 17, or the meeting portions of section 1 and attaching portion 17 can be formed angular, or, for example, square. This manner of connection, as shown at 17, can be applied not only at frame part 1, but wherever required for connecting two pipes.

The headpiecelti is shown with its center portion of contracted diameter as compared with the end portions, this constructionhaving been found to give strength. A name or other device can be pressed directly into this headpiece. The edge portions of the headpiece are doubled or turned inward into the tube or body 16 and then flanged, as seen at 20. The steering-post 21 extends through or swivels in the headpiece, and the flanges 20 can seat ball-races.

The connection 17is readily made by bending parts of the tube 16 inward to form lips .17, Fig. 3, which are'parallel if the frame part .1 is to swing or be adjustable or placed at an angle if the part 1 is to remainfixed.

The frame part 1 can be secured by a bolt or post, and the top or handlebar-carrying part.

The handle-bars 38 are showneach separately pivoted between the top parts of the. fork, Fig. 1. The handle-bars have disk-shaped end portions seated between the fork-sections, a pivot 39 in the fork, and disks ad justably'supporting the handle-bars, so. that the latter can be set higher or lower. When set, a pin or fastening 40 passed through the fork and disks fixes the handle in the'position series of holes for the reception of pin 40, Fig.

2. The steering-post parts of thefork-sec- 1 Y tions are concaved or formed intoh'alf-tubes, which when placed edge to edge can be clasped piece 16. 42 and a collar 43, removably screwed or-secured in place, and these parts 42 and43,

with the headpiece-flanges 20, form ball-races. The sleeve 41 can be riveted or fastened to the steering-postor intermediate fork part. I l 7' desire'to secure I WhatI claim as new, and by Letters Patent, is f 1. A cycleframe having post frame and a front branch each having its lower end flattened into semicircular shape, T

a tubul'ar I seat- X9 or held by sleeve or tube 41, fitting into head The tube has a bent or flangepart the fiat sides of said semicircular ends of they seat-post and front branch being arranged in n s or adjustmentrequired, the disks having a juxtaposition and secured together, substantially as described.

2. A headpiece made of a single piece of metal bent into tubular form and having its edges doubled inward into the tube and flanged substantially as described.

3. Acycle-frame having its frame branches each formed from a single piece bolted directly to one another, the front and intermediate branches being bent to form a hearing or crank-hanger substantially as described.

4. A cycle-frame having its steering-fork formed of two sections of flat or sheet metal, each section integrally comprising the lower or wheel-bearing part, the swiveling or intermediate part and the top or handle-barbarrying part, said lower part having its face or flat portion facing toward or in the plane of the wheel, its intermediate portion channeled witnesses. v
